SHEET-METAL DOOR, WAINSCOTING, &c.

Specification of Letters Patent.

Application filed. June 26, 1907.

T o all whom it may concern.'

Be it known that I, CHARLES E. NELLIs, a citizen of the United States,and a resident of the city and State of New York, county of Queens, haveinvented certain new and useful Improvements in Sheet-Metal Doors,VVainscoting, &c., of which the following is a specification.

rI his invention relates to sheet metal doors, walnscoting, etc., andthe object of the invention is to secure the component parts of suchdoors, wainscoting, etc. to each other in a simple and improved manner.

I will describe structures embodying my invention and then point out thenovel features in the claims. In the accompanying drawings :-Figure 1 1sa front elevation of a door constructed in accordance with my invention;Fig. 2 is a section on the line 2 2 of Fig. 1; Fig. 3 is a section onthe line 3-3 of Fig. 1; Fig. 4 is an elevation, partly broken away andpartly in section, of wainscoting constructed in accordance with myinvention; Fig. 5 is a .Vertical transverse section of Fig. 4; Fig. 6 isa perspective View, partly in section, of trimmings secured to a doorjamb in accordance with my invention; Fig. 7 is a horizontal section ofFig. 6; Fig. 8 is an edge view of the upper portion of the door showinga detail of construction.

Referring to Figs. 1, 2 and 3, 10, 10 indicate two plates or panels of alength and width substantially equal to the length and width of thedoor. Each plate is provided with a series of lugs or ears 11 which areformed by striking up portions of the metal wherever desired. As shown,these lugs project on each side of both plates and are arranged inVertical alinement and also in horizontal alinement. The lugs on theinner opposing faces of the plates receive and hold vertically extendingchannel bars 12 and horizontally extending channel bars 13, and thesebars serve to hold the plates 10, 10, in parallel relation to each otherwith a space hetween them.

The stiles or vertical rails of the door are indicated by 14, the topand bottom rails by 15, the molding connected to the stiles by 16, andthe molding connected to the rails by 17. The panels 18 on oppositesides of the door are formed by the portions of the plates 10, 10, whichare surrounded by the moldings tion of an end ed e of the door.

16 and 17. The stiles 14 are longer than the plates 10 and grooved bars21 and 23, and the edge portions thereof are cut out at the upper andlower ends so as to bring the upper and lower ends of the edge portionsflush with the upper and lower ends of the bars 21 and 23 when the partsare assembled. The upper and lower ends of the plates 10 will projectbeyond the ends of the bars 21 and 23 to an extent substantially equalto the depth of the grooves in bars 22. As shown the inner edge of themolding is formed with a return bend as indicated at 19, and this returnbend interlocks with the lugs 11. Also, as shown, each stile 14 and themoldings 16 on both faces of the door connected to it is formed from asingle piece of metal which also forms a side edge of the door, and eachrail 15 and the molding 17 on each face vof the door connected to it isformed from a single piece of metal which also forms a por- The molding16 is substantially the same length as the Stiles, as indicated bydotted lines in Fig. 1, but the molding 17 is mitered as indicated at20.

The parts of the door are assembled as follows: The two plates 10, 10,are first connected together by the channel bars 12 and 13 and then oneof the stiles and molding 16 is slid over the plates with the returnbends 19 of the molding interlocked with the lugs 11. The bar 21, whichhas longitudinal grooves to receive the side edges of the plates 10, 10,is then inserted between the metal forming the edge of the door and theside edges of the plates 10, 10. The rails 15 and molding 17 are nextslid over the plates with their return bends 19 interlocked with lugs 11and the molding 17 will overlap the lmolding 16. The other stile and itsmolding is then slid over the plates 10, 10,'with the return bends 19interlocked with lugs 11 and the grooved bar 23 is then inserted inposition. The grooved bars 22, 22 are then inserted in a way similar tothe bars 21 and 23 and the end portions of the stiles are then foldedover onto the bars 22 to complete the top and bottom edges of the dooras indicated by dotted lines in Fig. 8. The ends of the bars 22 are Hushwith the side edges of the door. The moldings 17 overlap the moldings 16and form copes and the mitered ends of the moldings 17 may, if desired,be

soldered to tne moldings lo. Also if clesired the rails 15 may beconnected to the moldings 16 by screws 24:.

Referring to Figs. t and 5 which illustrate wainscoting in which thecomponent parts are secured to each other in accordance with myinvention, a plate 25 is provided with lugs or ears 11 projectingoutwardly therefrom. The plate 25 is secured to a wall in any suitablemanner and to it top and bottom rails 26 having moldings 27 integraltherewith and said molding having a return bend 28 at its inner end edgeare secured by interlocking return bends 28 with lugs 11 as shown inFig. 5. Vertical rails or stiles 29 having integral moldings 30 are alsosecured to said plate in a similar manner. In this construction, themolding 30 will overlap the molding 27 and form copes. In thisconstruction one of the rails 26 is first fitted in position7 next thevertical rails 29 and then the other rail 26. The rails 26 also havelugs 11 formed thereon with which a cap piece 31, moldings 32 and footpiece 33 are interlocked.

In Figs. 6 and 7 a sheet metal door jamb 34 is provided with projecting'lugs or ears 11 with which a'door stop 35 and an architrave 36 areinterlocked.V

It will be observed vthat in all the struc-` tures illustrated the earsor lugs are entirely concealed by the molding or other part interlockedwith them. Also in Figs. l, 2 and 3 the plates 10, 10, are inclosed andhidden from View by the stiles and rails except their central portionswhich form the panels 1S.

I claim- 1. In a sheet metal door and like construction, a bottom railand a metal panel comprising parallel spaced plates having struck outtongues, and said rail plates having a molding portion with bent freeedge adapted to engage and interlock with said tongues.

2. In a sheet metal door, the combination of a plate having verticalrows of separated, integral lugs projecting from its surface and alsohorizontal rows of similar lugs, stiles having integral molding and thelatter having a return bend at its inner edge to interlock with theVertical rows of lugs, and rails also having integral molding with areturn bend at its inner edge to interlock with the horizontal rows oflugs.

3. In a sheet metal door, the combination of two opposing plates securedtogether in parallel relation with a space between them and each havingvertical and horizontal rows of lugs projecting from its outer surface,two stiles each formed from a single strip of metal and having a returnbend at each or its longitudinal edges to interlock with the verticalrows of lugs on the respective plates, and two rails each formed from asingle strip of metal and having a return bend at each of itslongitudinal edges to interlock with the horizontal rows of lugs.

4. In a sheet metal door, two opposing plates arranged in parallelrelation to each other and having rows of lugs projecting from theiropposing surfaces, and channel bars interlocked with said lugs toconnect said plates to each other and also hold them in spaced relationto each other.

In a sheet metal door, two opposing plates connected together with aspace between them, combined with sheet metal stiles and rails connectedto said plates and entirely inclosing the edge portions thereof, and thecentral portions of said plates forniing the door panels., and groovedbars inserted between the edges of said plates and the metal forming thestiles and rails, with the edges of the plates fitting in the grooves inthe bars.

6. In sheet metal structures, the combination of a plate having verticalrows of integral lugs projecting from its surface, and also horizontalrows of similar lugs, stiles having integral"`1'nolding with a returnbend at its free edge to interlock with the vertical rows of lugs, andrails having also integral molding with a return bend at its free edgeto interlock with the horizontal rows of lugs, the molding on the railsbeing mitered and overlapping the molding on the stiles to form copes,or vice versa.

7. In a fireproof door and like construction, the combination withpanels comprising parallel spaced plates having struck up lugs, and aportion provided with a lip to engage said lugs to secure said portionto the plates.

8. In a sheet metal door and like construction, the combination of ametal panel comprising parallel spaced plates having struck up tongues,and a molding portion with bent free edge to engage and interlock withsaid tongues.

9. In a sheet metal door and like construction, a metal panel comprisingparallel spaced plates having struck up tongues, means for securing theplates to each other, and molding portions with bent free edges toengage and interlock with said tongues.

In witness whereof, I have hereunto set my hand to the foregoingspecification in the presence of two subscribing witnesses.
